But visitors are unimpressed, giving it just one out of five in the ratings - the lowest possible score on the TripAdvisor site.

One reviewer called 'Ian S' who visited in January this year gave it one star and wrote 'Avoid if you can help it'.

Another traveller from Rome added that the restaurant is 'Just awful' adding: "if you read this get a sandwich from Boots and sit somewhere".

A regular visitor from Birmingham who works in Belfast has posted four reviews of the Harvest Market from December 2011 to June last year but each time found the restaurant failed to live up to his expectations.

Another reviewer from Glasgow added that the cooked breakfast was 'anti-food' and said the restaurant was 'embarrassing for Belfast'.

Zak from Tamworth added: "It's the last place people see before they leave the city and it leaves a bitter taste in the mouth".

The second-lowest ratings are given to the Lagan Bar & Restaurant, which is described as an 'informal bar' serving snacks, burgers and main meals including an £8 'Breakfast and pint' deal.

The most recent reviewer, Chris Harris from Liverpool, wrote in January this year: "Avoid at all cost!" adding that the BLT was 'inedible and missing ingredients'.

Out of 16 reviews, a total of thirteen awarded the lowest rating of 'terrible' although one visitor who reviewed the restaurant on Christmas Day did give the restaurant an 'excellent' rating.
